Formulas for Lightweight Concrete - Green Home Building

Q: We are trying to develop a lightweight pumice concrete here in South Texas. We tried some mix designs, but the compressive strength yielded has been low (400-500 psi). I was wondering if someone has developed a good mix design to yield an 1200-1800 psi design. We are using pumice from New Mexico and cement.
